Polysaccharide hydrolysis rates per time point in surface-water roller bottles. Time courses of arabinogalactan (Ara), chondroitin (Chon), fucoidan (Fu), laminarin (Lam), pullulan (Pull), and xylan (Xyl) hydrolysis in the surface-water roller bottles. Error bars are standard deviations of triplicates. Note the different scale of the y-axis for Xyl. DOI: https://doi.org/10.1525/elementa.371.f2
